Performance Analysis of Conventional Diversity Combining Schemes in Rayleigh and Rician Fading Channels
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 3
Abstract
Abstract: Diversity is the powerful technique used in wireless communication system to improve the performance over a fading radio channel [1] [2]. Here receiver is provided with multiple copies of the same information signal which are transmitted over two or more real or virtual communication channels. Basic idea of diversity is repetition or redundancy of information. In virtually all the applications, the diversity decisions are made by the receiver and are unknown to the transmitter. This paper deals with the different diversity techniques like Maximal Ratio Combining (MRC), Equal Gain Combining (EGC) and Selection Diversity (SC) and their performance evaluation over Rayleigh and Rician Channel under Binary Phase Shift Keying (BPSK) modulation. The performance of MRC, EGC and SC is analysed in terms of Symbol Error Rate (SER) and Signal to Noise Ratio (SNR) by varying L diversity branches from 1 to 4.
